    Abstract: A battery module includes a module housing, a safety compartment, electrical assemblies, and explosion-proof structures. The safety compartment, the explosion-proof structures, and at least a part of the electrical assemblies are located outside the module housing and are located on a same side of the module housing. The explosion-proof structure includes a connection end and a pressure relief end that are disposed opposite to each other. The pressure relief end is located in the safety compartment. The pressure relief end of the explosion-proof structure is located in the safety compartment, so that a high-temperature combustible fluid from the pressure relief end flows into the safety compartment, to prevent the high-temperature combustible fluid from flowing to another position of the module housing to burn the electrical assembly. The pressure relief end of the explosion-proof structure is separated from the electrical assembly by using the safety compartment, to avoid a secondary safety accident.

    Abstract: The energy storage system includes battery cells, a subrack, a backplane, and a battery management system BMS. The subrack reserves a plurality of battery cell slots, the battery cells are connected to the backplane through the battery cell slots. The backplane is installed in the subrack, a first power terminal is reserved at a position corresponding to the battery cell slot on the backplane, and a plug-in power terminal is formed by a second power terminal of the battery cell together with the first power terminal. A power circuit, a sampling circuit, and an equalizer circuit are integrated into the backplane, and the power circuit, the sampling circuit, and the equalizer circuit are connected after the second power terminal is plugged and docked with the first power terminal. The BMS is connected to the backplane for managing the energy storage system.
